Your answer made me look at the code, and now I think I'm confused.
No, I don't need/want a redundant env, I'm just trying to setup a persistent
env. on the SD card from which I boot.
The error that happen at "env save" also happen at boot (see previously
attached bootlog), and at "mmc dev 1 3" command, see below.
mmc 0 is the on-board soldered eMMC
mmc 1 is the SD card I'm booting from
I'm using a GPT partition table on both devices as I would on any other
block device, is that OK to save an environment ?
The test on following line is failing:
https://github.com/u-boot/u-boot/blob/master/drivers/mmc/mmc-uclass.c#L478
I've put a debug print after this test, and you can see it in the
following (at the end):
